Systems and methods for preventing digital key relay attacks are provided. A method includes determining a threshold response time for a wireless communications device to process a challenge. Determining the threshold response time may include determining a benchmark response time for the wireless communications device to respond to the challenge based on one or more conditions of the wireless communications device, and setting the threshold response time to the benchmark response time. The method further includes sending the challenge to the wireless communications device. The method further includes receiving a response to the challenge from the wireless communications device within a response time. The method further includes authenticating the wireless communications device based on the response time being less than the threshold response time. Associated systems are also provided.
Legal claims defining the scope of protection, as filed with the USPTO.
4. The method of claim 1, wherein the processor-load data is received by the authentication system when an initial connection is established between the wireless communications device and the authentication system.
5. The method of claim 1, further comprising sending, by the authentication system, a command instructing the wireless communications device to end one or more processes running on the wireless communications device.
9. The method of claim 6, wherein the processor-load data is received by the authentication system when an initial connection is established between the wireless communications device and the authentication system.
10. The method of claim 6, further comprising sending, by the authentication system, a command instructing the wireless communications device to end one or more processes running on the wireless communications device.
15. The system of claim 11, wherein the logic device is configured to query the processor-load data when an initial connection is established with the wireless communications device.
16. The system of claim 11, wherein the logic device is further configured to send a command instructing the wireless communications system to end one or more processes running on the wireless communications device.
